EBPECIPICATION forming part of Letters Patent No. 305,251, datedSeptember 16, 1884.

. Application filed March 10, 18953. (No model.)

To aZZ whom it may concern:

Be it known that I, ISRAEL TOWNSEND, a citizen-of the United States,residing at Ports mouth, in the county of Norfolk and State of Virginia.have invented certain new and use ful Improvements in Car-Ventilators;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference beinghadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

My invention has for its object the ventilation of railroad-cars frombeneath by forcing the air up through certain pipes by means of certainmechanical devices fastened to the bottom of said car and between thetrucks of said car.

My invention is illustrated in the accompanying drawings.

Like letters represent like parts in all the figures. a

Figure 1 represents a side View of railroadcar with my inventionattached ready for use;

Fig. 2, a broken-away end View of said car, showing a section ofreservoir or tank, with connecting-pipes; Fig. 3, a reversible blowerwith connectingpipes; Fig. 4, adjustable or split pulley attached toaxle or shaft of carwheel.

The letterA represents body of railroad-car; B, the horizontal piperunning along whole length of floor and 011 the inside of car, withsmaller perpendicular pipes I) open at the top, putting out of and beingattached to pipe B.

There are two horizontal pipes, B, and two sets of pipes, b, one on eachside of car, as shown in Fig. 2. The pipes 12 may be four feet inlength, longer or shorter, and may be provided with stop-cocks a, forthe purpose of preventing the passage of air when it is so desired.

5oder side of pipe 13, to which it is attached in such a manner as toallow the passage of air from one pipe to the other. There are twocurved pipes, c, as shown in Fig. 2. The reservoir or tank Oispenetrated by pipe d, which descends into tank 0 a greater or lessdistance.

with stop-cock g ,'to be used so as to open or close said water-pipe.

D D represent hollow metal pipes putting out from pipe (1 and radiatingso as to enter the metal case of blow-wheel, as shown in Fig.

1. Said pipes D D are provided with stop-' cocks cc, to be opened orclosed, as hereinafter shown.

E represents a reversible blow-wheel, provided with a metal casingsecurely fastened to the bottom of the car-body A. The blow-wheel E isso constructed that when the car is running in a forward direction itwillbe revolved by means of belt f, attached to pulley Gand to pulley q,so as to force the air into the hollow pipe D, when the stop-cock 0 willbe opened, so as to allow the passage of air through pipe D, andstop-cock 0 will be closed, so as to prevent the passage of air throughpipe D. XVhen the car is running in an opposite direction, theblow-wheel will be revolved in an opposite di' rection by means of saidbelt and pulleys, and force the air into hollow pipe D, when stopcock 6will be openedfso as to allow the passage of air through pipe D, andstop'cock a will be closed, so as to prevent passage of air through pipeD.

The circle F represents car-wheel. The dotted circle G represents theadjustable or slip pulley securely fastened to the shaft or axle 71. ofcar-wheel F, with belt f attached.

In Fig. 3 is given a detailed drawing of the reversible blower,consisting of blow-wheel E,

curved arm or band m, extending on both sides of blow-wheel, as shown indrawings, and containin g axle box or brass q, in which the journal ofaxle of wheel E revolves. There are two boxes, q-oue on each side ofwheelalso -partly inclosed by metal casing H, and the consisting of twohollow pipes or tubes, l) D, with stop-eocks c c.

In Fig. 4 is given a drawing of split pulley G, divided intohalfsections 9, said half-sections being held firmly together by meansof metal bands or straps i, which are securely fastened to both sides ofpulley G by means of bolts 91, passing through pulley G and straps i7,and being tightened by means of nuts. The hub or center of" pulley G isprovided with a metal box, 7;, which fits upon shaft or axle 71, and islocked to said shaft or axle by means of key Z in such a manner as toprevent said pulley G from slipping. Pulley G is provided with flanges,and is of suflieient width to prevent belt f from slipping ofi.

Then the car is in motion, the blow-wheel E will be revolved in such amanner as to force air into the pipes D D, as hereinbel'ore described;from thence into pipe d,- from thence into the water contained in tankG, where the air is nuritied of all dust or dirt; from thence intoandalong pipes B; from thence into both sets of pipes I); from thence intointerior of car A; from thence out at openings in top of ear, therebycooling, purifying, and ventilating said ear.

Having fully described my invention, what I desire to claim and secureLetters Patent for is In a car-ventilator, a reversible blower, E,provided with twin pipes D D, said pipes hav ing suitable valves tochange or check the current of air, and converging into pipe d, allbeing situated and operated beneath the ear, substantially as and forthe purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.-

ISRAEL TGXVIv SEND.
